Turntable stand, suggestions?

Hey Guys,

This is my second thread ever! This summer (I live in Australia- so summer is coming up for me) I've set myself a project to build a turntable stand for my Rega RP6.

I was wondering if you guys could give me suggestions as to what materials and shape you would suggest. Of course the main priority is to reduce vibration, isolating the turntable.

I want to use wood, I was also thinking about a nice thick slab of rock too...

I'm new to turntable isolation and would appreciate any wisdom.

You didn't mention what type of stand you are looking for.Wall mount or floorstanding.
It's a good idea to search this forum for projects.You can also look at www.diyaudio.com
there are projects there also.

I would recommend a wall-mounted, low mass rigid stand. Rega's own wall-mount works very well, and Target used to make a very nice welded wall-mount as well. High mass under a Rega doesn't tend to work very well, so I would avoid placing the deck on a slab or granite for example (granite looks nice, but has terrible vibrational properties). Other options to consider are a Gingko platform, or a small Symposium shelf.

And once again AK has taught me something very useful.
I was just about to put a nice granite slab that I found for a few $ in place in my system as an isolation deck for my cd player. I stumbled across this, and that led me to read more on the subject.
So now I suppose the granite will go to another use and I'll find something like slate or soapstone as a deck for the cdp.
Thanks, AK! :thmbsp:
 
Granite at least 3 inches thick.

It depends on what you are trying to do, sometimes in situations mass loading works well to drub out vibrations. Don't discard that block of granite yet, you might find a use for it like maybe an amp stand.
 
My stand is a 2" x 1/4" wall square tube base with a 4" x 10ga square column ( both filled with sand ) that supports a tool room grade granite surface plate. This works very well with my VPI HW19. My neighbor scored a used piece of Cambria countertop and cut a piece for his wall mount. He had used a piece of MDF before. The difference was pretty astonishing, so much so that I took the leftover piece and put it under my tube amps. Not expecting much and guess what. Big difference. Not as much as the turntable but very significant. Cambria really sharpens things up and adds detail without harshing things. I'm thinking of replacing the surface plate with this. Sorry for rambling.
 
FWIW: Run over to www.audioasylum.com and research Lack tables by Ikea in the Tweakers asylum or Vinyl asylum. Excellent discusssions on isolation systems and Hi v. Lo mass isolation. Good stuff and worth the read.

Thanks for the help. I was thinking of a floor standing unit. I'll sketch something now and upload it to the forum.

Here is a very rough diagram that I threw together in the last 5mins..

I hope this diagram makes sense. Its a basic stand design.. The top portion is a hollow rectangular frame (hollow when looking from the top) with 4-Square panels on the bottom for the isolation feet to fit on.

I thought it would be wise not to make it enclosed so that vibrations cant bounce around inside.

The stone (yet to be decided ) will sit on the isolation feet.
